The method involves subdividing data of file into families with blocks, assigning a specific identification parameter related to a descrambling module (Mj) to each family, and scrambling each block, during encryption phase, where j is a integer. The family of each block is identified and each block is descrambled by the module using a key (Kj), during descrambling phase. The module has a processing capacity and a specific level of security. An Independent claim is also included for a system for protecting scrambled data provided to a receiver terminal. |
